WQ Alpha Agent

Automated WorldQuant BRAIN alpha factor research agent — generate, simulate, diversity-check, submit, and evolve alpha expressions with LLM-driven automation.

wq-alpha-agent is an exclusive Python framework and agent skill for automated alpha factor research on the WorldQuant BRAIN platform. It packages hundreds of simulations worth of empirical knowledge into reusable building blocks, playbook templates, and self-evolving workflows.

Why This Exists

WQ Alpha mining is not just about writing more expressions. The bottleneck is the research loop:

• Finding usable fields fast enough
• Avoiding repeated low-Sharpe templates
• Controlling turnover before submission
• Checking SELF_CORRELATION against existing ACTIVE alphas
• Preserving lessons from failed simulations instead of rediscovering them

This framework packages that loop into agent-readable modules plus a self-evolution mechanism that turns each BRAIN interaction into reusable research rules.

Quick Start

1. Install

cd wq-alpha-agent
pip install -e .

2. Set Credentials

export WQ_BRAIN_USERNAME="your_email@example.com"
export WQ_BRAIN_PASSWORD="your_password"

Or create an untracked credential.txt:

["your_email@example.com", "your_password"]

3. Search Available Fields

# Search locally cached fields (USA TOP3000 delay=1)
wq-search-fields --search "operating_income" --category fundamental

# Fetch fresh field data from BRAIN API
wq-search-fields --fetch-all --save references/my_fields.json

4. Run a Research Batch

# Always dry-run first!
wq-batch --config examples/example_quality.json --dry-run --limit 2

# When you're ready (and have set auto_submit: true in config)
wq-batch --config my_research_batch.json

5. Learn From Results

# Preview lessons from your alpha history
wq-evolve

# Apply lessons to local database
wq-evolve --apply

6. Verify Submissions

wq-verify <alpha_id_1> <alpha_id_2>
wq-verify --input alpha_ids.txt --output verification_results.json

Using with Claude Code

Place this repository's SKILL.md in your project's .claude/skills/wq-alpha-agent/ directory alongside the Python package. Claude Code will automatically follow the playbook for:

• Designing alpha expressions from proven templates
• Selecting appropriate settings per factor type
• Diagnosing simulation failures
• Running and interpreting the diversity gate
• Deciding when to submit
• Evolving the skill from new empirical results

Key Design Decisions

Fingerprint-Based Diversity, Not Just Blacklists

The diversity gate normalizes expressions, extracts field/operator skeletons, and classifies alphas into families. It blocks candidates that are:

1. Exact normalized matches of protected alphas
2. Same field skeleton with only parameter/weight changes
3. Same family with high key-field and operator overlap

This catches near-duplicates that simple string matching would miss.

Daily-Return Correlation, Not Cumulative PnL

The framework always computes correlation on daily PnL changes, never on cumulative PnL curves. Cumulative PnL correlation is severely inflated (> 0.90 for almost any pair) and completely misleading for diversification decisions.

201 ≠ ACTIVE

A 201 response from the submit endpoint only means the request was accepted. The framework always follows up by polling until the alpha status resolves to ACTIVE or a SELF_CORRELATION failure is detected.

Empirical Foundation

Built from:

• 600+ BRAIN simulations
• 168+ batch research sessions
• 4,367 USA TOP3000 delay=1 data fields catalogued
• Failure pattern analysis: LOW_SHARPE (90.7%), LOW_FITNESS (66.2%), LOW_SUB_UNIVERSE_SHARPE (51.0%)
• Pass rate by type: Fundamental (40%) > Hybrid (12.7%) > Pure Technical (5.3%)

Safety Notes

These files are intentionally gitignored and should never be committed:

• credential.txt — BRAIN credentials
• alpha_db.json — Personal alpha records with PnL series
• batch_submit_results.json — Submission results
• .env — Environment variables
• Python caches and virtual environments

If you want to share research lessons, summarize them into general rules and add them to SKILL.md. Never publish raw alpha IDs, PnL series, or account-linked submission data.
